! Moderator Note Not your thread. Not the right place for you to advance your "theory"

What is the evidence that they have an internal structure? We've found evidence for all the particles we've discovered that have an internal structure - that we can cause excitations, and that we can break them up in some way.

Which is impossible under pure capitalism. If more people have money, that drives prices up. There will always be people who can't afford medical treatments. Tell me, what policies have conservatives implemented to ensure that we are all wealthy enough? They oppose a minimum wage. How do you get wealthy working for $8 an hour? Even if you work 2 jobs, that's $33,280 a year @40 hours a week. Probably less, because I don't think the GOP is a big fan of paid sick leave. How does the right feel about unions, who fight for higher wages? They are opposed to public education, which might allow people to get better jobs. If one hits a stretch of bad luck, what is the conservative stance on help for people out of work and possibly homeless, because they can't work? Sounds more like the conservative want you to have a unicorn, but it's just a talking point. So what? What business is it of yours what other people do in private? Where is your evidence of this? We had much better wealth equality back when taxation was much different. And see my remarks above about working for minimum wage. How successful is that at redistributing wealth? Where is your evidence of this? Of course you might be referring to tax cheats, et.al, as the best criminals, but on a dollar-by-dollar basis, I suspect that the rich are the worst criminals. The IRS estimates tax cheats cost the US $1 trillion a year. https://www.latimes.com/business/story/2021-04-13/tax-cheats-are-costing-the-us-1-trillion-a-year-irs-estimates Even if you had a million welfare recipients stealing $100,000 each every year, that's only 10% of the tax cheating. (and we could go into other white-collar crime and wage theft as well) Sorry, what? What unequal treatment do white males get? (here is another example of my observation about only dealing in generalities and manufactured outrage) Sorry, these are the fault of liberals in the US? And this suggests that the liberals you seem to dislike were supportive of these regimes. The left attacked the right? What history books are you reading? Since when is slavery a liberal tenet? (also, if you have to delve into history like this, it sounds like you have no arguments to make about politics of the current century) Why 25? If this is some age of responsibility then surely nobody should be able to do other things, like own a gun, before they are 25. Doesn't seem like a conservative view.

That would be in the way that 10^-35, while small, is still not zero It's not graviton; that name is reserved for the spin-2 boson that mediates gravity, or will, once a quantum theory of gravity is developed. You'll get a lot of traction telling the physics community that they don't understand physics, but not to worry, because you're coming to the rescue. Because physics works, and it's based on the mathematical descriptions. It would be quite the phenomenon to do high-precision experiments and have them be successful all while being a happy accident because the physics was wrong. This would include diagnosing the experiments when they weren't working, and being able to correct problems, all based on having the physics be correct. I'm pretty sure the reference was to your musings, rather than established physics. There is only some superficial overlap between the two.

Almost certainly. The thing is, people have been doing physics for quite some time, so the syntax is well-established. What you're doing is similar to showing up in a foreign country and expecting them to speak your language No, not really. KEf being final kinetic energy is fine, if you mean it the same as everyone else: the KE at the end of the example you're analyzing For difference we use ∆, so ∆KE = KEf - KEi So what you are doing is not "extending" the syntax, you are introducing new syntax where it already exists, which is confusing. ∆KE is not a KE that any one particle has, so it's a value for energy, but it's no longer describing the energy of a particle, so calling it a KE isn't correct. Example: Two 1 kg objects moving at 1 m/s collide head-on and stick together, coming to rest. Their change in KE is -1 Joule, but at the end of the example nothing is moving, so saying ∆KE is a kinetic energy is incorrect. There is nothing in that example that has -1 J of kinetic energy. A kinetic energy can't be negative. Yes, energy is conserved, but kinetic is only one form of energy. KE itself is not a conserved quantity. See the above example of a completely inelastic collision. As I have shown, ∆KE is not a value associated with any one particle, or even anything having motion. It is a useful value to know in may problems, but to be useful it must be properly labeled, so one can do a proper accounting of the energy present. Well, that's your problem. Calculus works regardless of your understanding or dislike of it. I agree that ∆KE = 0. That's the problem. You had said KE=m*(vf2-vi2)/2, rather than saying this was ∆KE IOW, you were claiming that some object's KE was described by the equation. And for an object moving at some constant speed, it's kinetic energy is decidedly NOT zero. For an object not starting from rest, this does not give the object's KE. Which makes your equation wrong.

Not really. It's still there, as noisome as ever. But you seem to be confusing freedom of speech and freedom from consequences. And you think your ignorant intuition must be correct? What efforts do you take to check to see if your intuition isn't misguided? Many conservatives also decry education. There's a fix for having to rely on intuition, but they avoid it, fervently. No, I think that nobody has dismissed what you say owing to grouping you in with other conservatives. In your closed thread, I don't think anything there was indicative of a conservative view. It was challenged on the claims you made but refused to substantiate. You had plenty of opportunity to present your case. You failed to do so. But you don't seem to see this as a failure, you blame others for this. In some instances. We're both moderators, and both enforce the law. My moniker (evil liar, or so I'm told) and current avatar came about because someone thought I ran the place. (AFAICT it's consistent with a persecution complex. You focus on whoever is telling to straighten up and fly right) Another common response. Despite the fact that you have broken specific rules, which have been pointed out to you, you choose to see this as "being hassled by the man" because of your views. I suppose it helps preserve your worldview. I will note that you still have not articulated any of your specific beefs with "the left"

What chapter of Serway talks about loop quantum gravity? The big bang, based on general relativity, doesn't cover the beginning as a point, since it breaks down when you approach a singularity. It goes back to ~10^-43 seconds, but before that you need a quantum theory. So no t=0, no point. A wave function isn't made of anything. Light does not require a medium. You're focusing on the analogy as if it were the actual science, which is a common mistake. Some physicists care, and work on foundations of physics. Others test to see if they are actually constant. But physics is a pretty big tent, so many of us go on about our jobs without having to worry about these questions, as there is no real impact on the work we do. Models require more than this. Wave functions are not bosons, and the dictionary is not a technical resource. "Graviton" is already taken. The universe is expanding faster than c, which would be impossible if spacetime were a substance.

Positive and negative come out of the math so you'd have to make changes in the equations, and some of them really wouldn't work anymore. The choice of what is zero is arbitrary but since what you are interested in is the change in energy between two states, it's often moot. if you chose a nonzero number you'd have it in two places that are subtracted, so it would cancel. Adding more terms that don't matter is kinda pointless.

The energy of binding for electrostatic and gravitational interactions is negative, that is, you have to release energy to form a bound system. It’s an energy deficit, as compared to having free particles, so there is no energy bound up in the bonds.

One thing I’ve noticed about folks with similar stances is that they never seem to be able to articulate what their specific issues are. It’s always some vague complaint, often citing some caricature of the group they are railing against. Manufactured outrage, based on propaganda rather than fact. I note that you aren’t denying that you’re failing to follow the rules, only that you see it as a burden and blaming others for it. Am I the chief or the sidekick?

It’s a geometry and the speed of light is involved. Yeah, this makes little sense.

Fiction and hallucinations have been around even longer than that. This would follow from “There is no evidence that they came here” Flawed reasoning. Superstring theory is only a small part of physics, so it can’t be used to represent the whole. Theory work is crucial to advancements. What innovations in physics have come about because of new age crystals?

Argument from personal incredulity is a fallacy. Zero seems to me like something that requires no preparation at all. Spacetime is a geometry, not a substance. It’s not “made of” anything, any more than a shape (triangle, cylinder) is made of anything.

Shortest recorded in the last ~50 years, but reconstructions show it was faster in the past, and we’ve gone to negative excess length of day in the atomic clock era. In the early 2000s ELOD was negative during part of the year. No leap seconds were inserted for 7 years. Then the days got longer again. https://www.ststworld.com/understanding-day-length-fluctuations-what-they-are-and-what-causes-them/ Even with the fluctuations, you can see the long-term trend is toward longer days, and that we’ve had negative ELOD in the 1930s and a much larger dip from ~1860-1900 https://geodesy.geology.ohio-state.edu/course/refpapers/dLOD_1800-2000.pdf Earth rotation rates have geologic- and climate-related contributions, so focusing on very short time scales is a tad misguided

Atomic fountain clock. To reduce scattering with background gases, the device is run under high vacuum. It attaches to a controller which provides the high voltage needed and measures the pressure.

This stuff is debunked elsewhere, so there's nothing new, but more to the point, there hasn't been any evidence presented! Trying to cast this as a discussion that has any merit is foolhardy.The OP was afforded an opportunity to present evidence and they chose to not even try.

! Moderator Note You were told not to bring this up in other threads when your original foray into this was locked. Those pesky rules, ruining your fun...

! Moderator Note You are free to post your musings on a blog somewhere, and the government can't throw you in jail to stop that. That's freedom of speech (here in the US, at least). This freedom does not involve being free from repercussions for that speech. But this site is not the government. We have rules, designed to facilitate discussion, and you are expected to follow them. Included in those rules is providing evidence to back up what you say.

! Moderator Note Post the information here, as required by the rules

No

We have used ion pumps for our clocks since we wanted what is ultimately an oil-free system for long-term operation, though we use a turbo + mechanical pump to get down to the pressure where the ion pump will start. I used a diffusion pump in grad school. Luckily it never vented to air while operating, so I never had to clean up the resulting mess. I put various interlocks in place to shut pneumatically-operated gate valves in case it was exposed to higher pressures (like if there was a serious leak) and shut things down if the pump cooling was interrupted.

I would add that the photon does not require any external field. No photon, E and B have zero amplitude. There is no analogue of the rope present.

Where (i.e. in what context) does this term show up? AFAIK it's not phrasing that's used much in QM. An electron is a wave. The "cloud" in this description is a probability of finding it somewhere if you were to try and localize it; the probability function looks like a cloud. But one has to not try and impose notions of classical physics on this description - it would be incorrect to think of the electron existing at specific points at times when you aren't measuring it, and that it's moving from place to place. Because it is a wave, it exists everywhere.

You said orbit, and said it implied movement. There is no denying that. And by using the terminology and description, you give the impression that you don't actually know the correct model. You suggest that I made an unwarranted conclusion, but I say I made one based on the evidence before me. If it's the case that you misspoke, then all you have to do is say that, and we can move on to the next point about how we had gone from energy to movement; the original claim was about the latter, not the former. That's not what I said, so I will you refer you to your own comment about snarky responses. What I want is for people to be able to back up what they claim, and to have put in the minimal effort of learning the basics, rather than going on some wild conjecture. I will repeat: the claim was not in the OP, and was not phrased as a question. I was presented as a fact. You followed up with "As far as my imagination takes me, if no energy moved in the universe, there would be no time expended." Which is fine as a concept to explore, but you have to be prepared to defend it, or you can accept responses from people who are correcting misconceptions. You've been fighting that.
